Lee Oilfield Service Ltd

A jar has to deliver the right impact downhole after heat, torque, and hole conditions change the job. Lee Oilfield Service Ltd. works from Edmonton on hydraulic oilfield jars for drilling and fishing applications.

We manufacture, assemble, service, test, and rent jars built from Canadian-made components. The shop machines critical areas to close tolerances, uses heat-treated 4145H or better steel stock, and can modify designs for special operating conditions.

Servicing is handled as a full teardown and test path. Jars are tested before dismantling, cleaned, inspected, checked with magnetic particle or ultrasonic techniques when parts are in question, rebuilt with new seals and hydraulic fluid, then tested again against published operating values.

Lee Oilfield has more than five decades of jar-use experience behind its product work. H2S-resistant tools are available on request, and rental terms are published for jobs that need jar access without a purchase.
